While matplotlib compiles fine with lower versions of pyparsing, some functions (at least savefig() when using mathtext) cause runtime errors that disappear after uprading to pyparsing-1.5.1. Normal plots (something like "show(plot(linspace(0,2*pi,100)))") still worked, though. If requested, I will post a test script. Reproducible: Always Steps to Reproduce: 1. emerge =dev-python/matplotlib-0.98.5.2-r1 with <dev-python/pyparsing-1.5.1 2. plot something with a mathtext label (r'$blah$') and save a figure with savefig() Actual Results: Traceback (most recent call last): File "signals.py", line 49, in <module> savefig(fname, dpi=150, papertype='a5', format='eps') File "//usr/lib64/python2.5/site-packages/matplotlib/pyplot.py", line 345, in savefig return fig.savefig(*args, **kwargs) File "//usr/lib64/python2.5/site-packages/matplotlib/figure.py", line 990, in savefig self.canvas.print_figure(*args, **kwargs) File "//usr/lib64/python2.5/site-packages/matplotlib/backend_bases.py", line 1419, in print_figure **kwargs) File "//usr/lib64/python2.5/site-packages/matplotlib/backend_bases.py", line 1308, in print_eps return ps.print_eps(*args, **kwargs) File "/usr/lib64/python2.5/site-packages/matplotlib/backends/backend_ps.py", line 869, in print_eps return self._print_ps(outfile, 'eps', *args, **kwargs) File "/usr/lib64/python2.5/site-packages/matplotlib/backends/backend_ps.py", line 895, in _print_ps orientation, isLandscape, papertype) File "/usr/lib64/python2.5/site-packages/matplotlib/backends/backend_ps.py", line 969, in _print_figure self.figure.draw(renderer) File "//usr/lib64/python2.5/site-packages/matplotlib/figure.py", line 772, in draw for a in self.axes: a.draw(renderer) File "//usr/lib64/python2.5/site-packages/matplotlib/axes.py", line 1601, in draw a.draw(renderer) File "//usr/lib64/python2.5/site-packages/matplotlib/axis.py", line 710, in draw tick.draw(renderer) File "//usr/lib64/python2.5/site-packages/matplotlib/axis.py", line 193, in draw self.label1.draw(renderer) File "//usr/lib64/python2.5/site-packages/matplotlib/text.py", line 452, in draw bbox, info = self._get_layout(renderer) File "//usr/lib64/python2.5/site-packages/matplotlib/text.py", line 253, in _get_layout clean_line, self._fontproperties, ismath=ismath) File "/usr/lib64/python2.5/site-packages/matplotlib/backends/backend_ps.py", line 308, in get_text_width_height_descent self.mathtext_parser.parse(s, 72, prop) File "//usr/lib64/python2.5/site-packages/matplotlib/mathtext.py", line 2806, in parse self.__class__._parser = Parser() File "//usr/lib64/python2.5/site-packages/matplotlib/mathtext.py", line 2096, in __init__ start_group = (Optional(latexfont) -
